In the Spotlight

Food: An Atlas – June 11, 2014The cropland and pasture data distributed by SEDAC are presented as cartograms, in which land area is replaced by extent of crops and pastures, to better visualize the global distribution and production of food around the world.

Data Use - Population and Burned Areas Around the Globe

PLoS ONE – February 7, 2014Research based on data from SEDAC’s Gridded Population of the World collection and burned area maps based on NASA’s MODIS satellite observations is helping to untangle the complex relationship between population density, land use and fire.

Data Use - Carbon Dioxide Emission Patterns and Population

Geophysical Research Letters – January 31, 2014Using measurements from NASA’s Measurement of Pollution in the Troposphere (MOPITT) instrument and SEDAC’s Gridded Population of the World data researchers are able to better understand global carbon dioxide emissions.

Map Gallery - Coastal Water Quality Indicators

Indicators of Coastal Water QualityA data and map collection based on chlorophyll-a concentrations derived from NASA's SeaWiFS instrument to analyze trends in near-coastal water quality from 1998-2007 that may affect coastal and marine ecosystems.

Map Gallery - Global Distribution of Human Population

Gridded Population of the World, Version 3 (GPWv3)GPWv3 data collection provides globally consistent and spatially explicit human population information and data that are compatible with data sets from social, economic, and Earth science fields to support interdisciplinary research.

Map Gallery - Satellite-Derived Environmental Indicators

MISR Instrument on the NASA Terra SatelliteGlobal Annual PM2.5 estimates of annual average grids of fine particulate matter (solid particles and liquid droplets) that were derived from MODIS and MISR satellite data.

Tools and Apps - Population Estimation Service (PES)

The Population Estimation Service is a Web-based service for estimating population totals and related statistics within a user-defined region. The service is accessible through three standard protocols: OGC-WPS, ArcGIS-REST and ArcGIS-SOAP.

Tools and Apps - SEDAC Map Viewer

The SEDAC Map Viewer is a Web mapping tool for visualizing all SEDAC map layers. The viewer organizes the layers into approximately 15 interdisciplinary topics (themes) that can be selected by users.

Tools and Apps - Ramsar Wetland Sites Mapper

The Ramsar Wetland Sites Mapper is a Web-based service for assessing the exposure to sea level rise of coastal wetlands designated as Ramsar Wetlands of International Importance (Ramsar Sites). The service supports WMS and WFS protocols.
